His efforts to protect himself then, and continuing until June, have not served him well, police said.

Hernandez, of Perth Amboy, recently was indicted by a Monmouth County grand jury on multiple charges, including attempted murder and other charges involved with the Feb. 26 stabbing and a new charge of witness tampering between March and June while he was in the Monmouth County Jail.

The indictment charges Hernandez with first-degree attempted murder, second-degree aggravated assault, third-degree terroristic threats and criminal restraint, witness tampering and possession of a weapon for an unlawful purpose and fourth-degree unlawful possession of a weapon.

The couple fought late on Feb. 25 and in the early-morning hours of Feb. 26. Police say Hernandez stabbed his girlfriend and restrained her in a Carr Avenue home. Much later, he drove her to the hospital while threatening to hurt her if she reported the assault, police said.

She was treated and released. The next day, she found a way to call police and Hernandez was arrested, police said.

But between March 1 and June 3, while Hernandez was incarcerated, he prevented the victim from cooperating with law enforcement, even though she was legally summoned by the court, the indictment alleges.

Hernandez has been in jail since his initial arrest in lieu of $567,500 bail.

The Asbury Park Press asked the Monmouth County Prosecutor’s Office for a photo of Hernandez, but they declined. State law allows authorities discretion in releasing suspect photos.
